The engine model is a set of codes used to identify and distinguish engines of different types, specifications or designs. It consists of several parts, including the head, middle, rear and tail, each of which represents different information, such as product series symbol, number of cylinders, stroke, cylinder arrangement, etc. For example, EA211 is an engine model of Volkswagen, which uses all-aluminum material and cylinder shutdown system to improve fuel economy.
The head usually represents the product series symbol and the generation symbol, which can be set by the engine manufacturer, but it needs to be approved by the relevant department.
The middle contains information such as the number of cylinders, stroke, cylinder arrangement and cylinder diameter of the engine.
The rear indicates the structural characteristics and usage characteristics of the engine, usually expressed in letters.
The tail is the symbol used by the manufacturer to distinguish.
In addition, the different parts of the engine model can reflect the engine's power source (such as diesel, gasoline), the working mode of the intake system (such as naturally aspirated, turbocharged), the piston movement method (such as reciprocating piston, rotary piston) and the cylinder arrangement type (such as in-line, V-type, W-type, etc.).
